CT CDL HazMat Practice Test 3 2025

Perfect for first-time and renewal CDL/CLP applicants, and those adding endorsements.

This third CT HazMat practice test contains another set of 30 multiple-choice questions based on the official CDL manual. Just like our other practice tests, this one is also designed to prepare you for the HazMat portion of your 2025 Commercial Driver’s License exam. There are several answer options, but only one of them is correct. Each question also includes a hint and an explanation. It is recommended that you check each question’s explanation to gain some further insight into the rule being tested. Every time you answer a question, you’ll get immediate feedback with a detailed explanation, so you won’t need to wait until the end of the test to know the correct answers. Good luck and drive safely!

Practice questions were identical to the actual HazMat test in Connecticut.
All of the material made it easy to study. I spent a few hours across 2 days going over the material and felt completely confident in passing. I passed with 25 questions (1 incorrect, overthinking it). This was also way easier and price was better than attending the trucking school where I obtained my CDL.
A
Excellent course.
I used this course to get my hazmat. It was easy to use. I appreciated the audio and visual format of the course. There were so many practice questions which was super helpful to pass the test. I took my test and passed with 100% in less than 5 minutes!
JS
I have been driving truck for almost 34 years.
I have been driving truck for almost 34 years and held a hazmat endorsement for quite a few of those years. DMV could not find any records of my hazmat endorsement, so in order to get my hazmat, I was required to take the ELDT training. I reluctantly put the money out for the training, passed and got my certificate. All said and done, I'm glad I did, because not only did it help me to remember some of my previous training, but I learned there was a lot I didn't know. I would recommend it to every driver.
SAD
I was able to do my ELDT online.
I was able to do my ELDT online and it was submitted immediately! I went to DMV and was in the system. Couldn't believe how quick it was! Passed my Hazmat endorsement test 1st time out. The information contained in the coursework made it a breeze to pass!
